Be it known' that I Enw' inTA-rnon, a citizen of the UnitedStates,residing at Farmingdal, Long Island-{New York, have inventedcertain new and useful Improve- 'nients in Compositions-fContainingvulcan-s ized Oil and Processes of Manufaetur gof which thefollowing',,-is afs'pecificatiolii" 1 This invention relates 'toaproduct ioinfled.

Its novel features w 1 be apparent from'the following description. i

' partsfof oil, I1 5O p'arts of sulfur and 4:0 parts ofclay produce aspongy. mass, very hardand containinga large percentage offree sulfur,while a mixture containing 100 parts oil, parts of'sulfur and 40 partsofclay= gives a mass very elastic under compression,- andapparentlycontaining all its sulfur 'in combination. In any case,-,I preferablyind the above spongy masses to as. fine a state of division" aspra'cticalto aid subs quent operations. I 'now'add to the abovcomminuted mass, a composition. containin I a nitrated oil or resin anda nitrocellulose having preferably a contentgof nitrogen of less thantwelve per centa The proportions of these ingredients mayvaryvwithin-wide limits,- as may also th'e nitrogencontent but -I have foundby experiment that the new.

nitrogen, may be added to 100v parts of the above vulcanized oilor'i'esin, and thismay be taken as astandard-Q.

" The nitro-oil and nit o-cellul'ose are mixed at atem-perature of 212P.to 250 F. and heating continued until the'nitro-cellulose is-disvsolved b .theoil. Instead df'dissolving the 'nitro-cel ulose in theoil,-which is a some- "what slow opera'tiom' I may dissolve both inaycommon solvent such as acetone, this solvent being driven'otl andrecovered after solution ensues; In either event, the adinixed.nitro-oil and cellulose is now added to say, an equal. amount of thefinely divided Qvulcanized' oil, the mixture heated and incorporated onhot mixing rolls until the nit foil and nitrocellulose combine with.tl'"

ulcanized oil. The resulting product is y verv elastic-and rubber-likeand-is suitable m'aking this composition; 1 use? a a ffo'r insulatingflexible wires, etc. As a modi- "fication of this process I may add thespongy vulcanized oil containing an excess of sul- -,;ffur 'to'a mixtureof a vulcanizab'leoil, ni-

trated oil and nitro-cellulos'e, mixing and heating them with or withouta common sol- "vent'until combination ensuesand part of thenitro-radicalis replaced by sulfur. The nitro-cellulose composition tends to addtoughness and tensile strength to the product and as its proportion isincreased thetoughness increases. The product thus produced is elasticand soft and is of such anature as to takethe place of rubber tubes usedfor insulating wires. It is also adapted for use as theltops of rubberboots and for other similar uses: l I

Itth'e proportionof the spongy mass is increased the'product is more,elastic under compression and resists the act-ion of acids betterybutit has'less tensile strength. It sired'I niay add clay to the'mixture ofthe spongy-mass and nitro-cellulose product and tion'harder.

With

:will have the efi'ect' of rendering the out 'limitlng' myself to thepropor 4. A composition containing. about 100 parts vulcanized oil andclay,- 9O parts nitrated oil, and about 10 parts nitro-cellulose.

5. A composition containing vulcanized oil, clay, nitrated oil,-vulcanizable oil and intro-cellulose.

G. A composition containing nitrate'd oil, nitro-cellulose, clay,over-vulcanized oil and sulfur. 4

8.- The herein 'described process consisting in vulcanizing oil in thepresence of clay and anexcess-of sulfur, grindin the product andallowing it to cool, and mixing said product thoroughly with .a solutioncontaining nitrated oil and nit-ro-cellulose.

9. Theherein described process consisting in vulcanizin oil in thepresence of an excess of sul ar, grinding the product and allowing it tocool, and mixing saidproduct thoroughly with a solution containing ni-vtrated oil and nitro-cellulose. v

10. The herein described process consist ing in vulcanizing oil in thepresence of an excess of sulfur and a clay containing 'sulfur,comminuting the product, and mixingit at a temperature below thevulcanizing temperature with a solution of nit-rated oil andnitro-cellulose.

11. The process consisting in maintaining oil or resin ata vulcanizingtemperature in the presence ofa vulcanizing agent until the vulcanizingoperation is completed, and mixing the product so obtained with anitratcd oil or resin and intro-cellulose maintainml at a vulcanizingtemperature until part of the nitro-radical in ,the 'nitrated oil andnitro-cellulose is replaced by the vulcanizing agent. p
